Mutated genes

Locus name Alias Hormone Mutated site Paper description
AT1G08260 ABO4 abscisic acid T-DNA inserted in 3972aa Similar to POL2A, DNA polymerase epsilon catalytic subunit. Essential for Arabidopsis growth. Null homozygotes are embryo lethal, partial loss of function alleles show embryo patterning defects such as root pole displacement. Delayed progression through cell cycle results in embryos with smaller numbers of larger cells.
